Cell body reorganization in the spinal cord after surgery to treat sweaty palms and blushing

The amount of compensatory sweating depends on the patient, the damage that the white rami communicans incurs, and the amount of cell body reorganization in the spinal cord after surgery.

After severing the cervical sympathetic trunk, the cells of the cervical sympathetic ganglion undergo transneuronic degeneration
After severing the sympathetic trunk, the cells of its origin undergo complete disintegration within a year.

The second thoracic sympathetic ganglion was most commonly located (50%) in the second intercostal space

anatomic variations of the T2 nerve root

6 (9.1%) sides showed a single large ganglion formed by the stellate and the second thoracic sympathetic ganglia. The second thoracic sympathetic ganglion was most commonly located (50%) in the second intercostal space. Conclusion: The anatomic variations of the intrathoracic nerve of Kuntz and the second thoracic sympathetic ganglion were characterized in human cadavers.

Abstract
Rats with chemical sympathectomy, induced either at neonatal age (long-term sympathectomy) or in adult animals (short-term sympathectomy) by guanethidine or by 6-hydroxydopamine, were used to determine the contribution of sympathetic noradrenergic fibres to afferent neuron-mediated responses and to non-neurogenic inflammation in the rat. Following long-term sympathectomy with 6-hydroxydopamine there was a 66% depletion of noradrenaline in the paw skin. This was accompanied by a 20-53% increase in the levels of sensory neuropeptides in the paw skin and sciatic nerve. A hypersensitivity towards heat stimuli was observed in the tail immersion test.

Drawbacks of thoracoscopic sympathectomy

Side effects after thoracoscopic sympathectomy have been discussed
widely in Taiwan society in the past few months. Lots of people in Taiwan
suffer from hyperhidrosis palmaris. Thoracoscopic sympathectomy is covered
by our National Health Insurance, and yet patient billing for this
operation does not exceed US$ 60. This is why this operation is so popular
here (1). However, patients with serious compensatory sweating must change
clothes several times a day (some complain they change as often as 10
times a day), resulting in a serious impact on work and social
interaction. Patients suffering from such serious side effects in Taiwan
have formed a support group based on an Internet discussion forum to
request the government to take this problem seriously
(http://home.pchome.com.tw/family/vivi12175/). Since October 2004, The
Department of Health Executive, Yuan, Taiwan, has prohibited surgeons from
performing this operation on patients under 20 years of age. To our
knowledge, this type of Internet-based support group also exists in
England (http://www.noetsuk.com/), Sweden
(http://home.swipnet.se/sympatiska/index3.htm), Australia (http://www.ets-
sideeffects.netfirms.com/), Spain
(http://www.terra.es/personal8/hiperhidrosis/principal.htm) and Japan
(http://www.geocities.jp/etscontroversialop/index.html). Thoracoscopic
sympathectomy is a relatively safe and simple procedure, however, the side
effects are potentially devastating. All surgeons who do the operation and
individuals preparing to undergo this treatment should know this well.

The Effects of Thoracic Sympathotomy on Heart Rate Variability in Patients with Palmar Hyperhidrosis

Compared with preoperative variables, there was a significant increase in the number of adjacent normal R wave to R wave (R- R) intervals that differed by more than 50 ms, as percent of the total number of normal RR intervals (pNN50); root mean square difference, the square root of the mean of the sum of squared differences between adjacent normal RR intervals over the entire 24-hour recording; standard deviation of the average normal RR in- terval for all 5-minute segments of a 24-hour recording (SDANN) after thoracic sympathotomy. Low frequencies (LF, 0.04 to 0.15 Hz) decreased significantly.

Patients with surgical sympathectomies have low plasma levels of DA and NE [49], whereas EPI:NE ratios are increased

Patients with surgical sympathectomies have low plasma levels of DA and NE [49], whereas EPI:NE ratios are increased (unpublished observations), suggesting decreased sympathetically mediated exocytosis and compensatory adrenomedullary activation.
